Automatic transformation of XML namespaces/Relations to other standards
Resource Directory Description Language (RDDL) may be linked from our RDF by the
:link element with
:role="http://www.rddl.org/". The meaning of
:purpose attributes is described by Associating Resources with Namespaces, this is incorporated into this specification by reference. RDDL specification advises to place an RDDL document at the namespace URL. This is discouraged by this specification which advises to put an RDF document conforming to this specification at the namespace URL. It is recommended that validation is described by means of this standard, not backward compatible :link element.
